CONWAY (AP) — Lawyers for a woman charged in Faulkner County in the death of her boyfriend want a judge to bar statements she made to police from being repeated before a jury.

The defense argued in a written motion that Jamie Lynn Leach of Quitman was coerced into speaking to an investigator after the Aug. 20, 2012, slaying.

The Log Cabin Democrat reported Leach was arrested later the same day. He is charged with first-degree murder in the death of 24-year-old Cody Bradley, who was found in their bathtub, dead from a gunshot wound.

Leach’s lawyers claim an investigator who interviewed her for three hours made a false promise of “leniency or reward” by telling her he wanted to help her.

A hearing had been set for Monday, but it was delayed until Dec. 12.

The defense said that investigators administered a polygraph test to Leach, whose answers didn’t clear her of the killing. After more than two hours of questioning, the defense said an investigator told Leach, “I want to go out there and fight for you.”

The investigator went on to say, “I want to fight for you from the time we leave this room to the time all of this plays out. And it will play out. I’m good at what I do.”

Leach’s attorney, Frank Shaw, argued that the investigator provided “a false promise of leniency or reward,” which should put Leach’s confession off limits in a jury trial.

If convicted of first-degree murder, Leach would face a sentence of 10 to 40 years or life in prison.
